Separation of normal paraffin's from branched-chain and cyclic hydrocarbons, removal of H2S, CO2 and mercaptans from natural gas

5A Molecular Sieve

It is mainly applied to separate isomerism alkane,Meanwhile, it can also absorb the molecular which can pass through in 3A and 4A Molecular Sieve and whose diameter are less than five angstrom. Expecially the result is very evident in the changing pressure absorption system.

Formula:3/4CaO.1/4Na2O.Al2O3.2SiO2.9/2H2O

Composition: 0.80 CaO : 0.20 Na2O : 1 Al2O3: 2.0 ± 0.1 SiO2: x H2O

Description	Divalent calcium ions in place of sodium cations give apertures of ~5Å, e.g., all 4-carbon rings, and iso-compounds.
Major Applications	Separation of normal paraffins frombranched-chain and cyclic hydrocarbons; removal of H2S, CO2 and mercaptans from natural gas
